We all like to catch fish but,,, We also know how fragile trout can be... Now I'm sure the fish were handled with care but do we know for sure that they all survived??

Here is an article from CT..

Here is one mortality report

Now that we've covered the basics of preserving your catch for the dinner table, lets look at the proper etiquette for releasing fish. A recent study done at Queens University in Ontario, Canada which looked at physiological effects of brief air exposure in exhaustively exercised (played out) rainbow trout (oncorhynchus mykiss), is very revealing and educational toward showing just how precarious and detrimental, improper catch and releasing fishing can be. I will be the first to say that even as a professional fishing guide and well accomplished recreational sportfisherman, I did not know all the facts when it comes to releasing the quarry of my angling efforts.

I will attempt to share with you the most scientifically substantiated information I have seen on catch and release methods. The study looked at survival rates of played out rainbow trout that were also exposed to air for 60 seconds, 30 seconds, and 0 seconds. Additionally, the survival rates on non-exercised rainbow trout were used as a control for the study. Get ready, the results are surprising.

As you'd expect, the control group had a 100% survival rate. The rainbow trout that were exhaustively exercised and not exposed to air survived at an 88% rate. However, the rate of survival for fish exposed to air for 30 seconds was only 62%, and those that were held out of the water for 60 seconds had a mere 28% chance of living to fight another day. The researchers attributed the higher mortality among fish exposed to air to a significant reduction of oxygen content in the fish's blood.

If these statistics leave you wondering or unconvinced, consider the following analogy: Holding a fish out of the water for 60 seconds or even 30 seconds would be like a human running full speed for a half an hour and then immediately being submerged in water for up to one full minute. Many of us would not fare very well under those conditions and if we did survive, we'd surely carry some ill effects, some possibly permanent.

This study will change the pace of my Kodak moment and expedite the time it takes me to put my catch back into the water. Ideally, keeping the fish submerged in the water while you take pictures will help tremendously toward making sure the fish doesn't eventually go belly up.

Some other important methods for handling fish you intend to release include touching the fish as little as possible, not squeezing the fish, and never putting your fingers inside the fish's gills. The more you handle a fish and run your hand(s) along its sides, the more that fish is likely to be depleted of its protective slime layer, thus increasing its risk of fungal infection and decreasing its ability to gracefully cut through the water. See also the article on how to release fish.

I like to run my hand along the leader to the fish's mouth and grasp the hook firmly until I can pinch it with a pair of pliers, using the weight of the fish to pull it loose. A lot of times (unless the hook is in an awkward position) I don't even touch the fish at all. When you hold a fish by squeezing it in the palm of your hand, you are not only removing its protective slime, but also possibly injuring its internal organs.

Equally important and potentially life-threatening to the fish is putting your finger(s) in their gills. A fish's gills are among their most fragile and crucial organs. Evolution has provided them protective gill plates to prevent anything from entering or piercing this fragile area. But unknowing anglers will routinely use this gill plate to hold their catch and although this is fine when you intend to keep the fish, it's a bad deal if a release is planned.
